D2, a 6V8 zener fed by R5, holds both tube cathodes at 6.8V;\n# VR1 (REST) takes VP a little under that, where the bars just show.\n# COLD: the thermistor over R8 is a divider that falls as the air cools.\n# C6 passes only the change onto CIN1, which R9 holds at VP (D3/D4 let a\n# big jump settle fast). IC2A gains it around VP, 5 to 215 times by the\n# COLD pot, and R12 takes the result to the left tube grid. Colder pulls\n# the grid negative and the bars grow.\n# LIGHT: the same again with the LDR over R13, C8, R14 and IC2B.\n# No high voltage on this board.
